Using Three Different Final Irrigants and Showing Their Effects on the Success of Revascularization

Assessment of Implementing Nano-technology in the Irrigation Protocol of One Step Revascularization For Necrotic Mature Teeth

this study will assess different irrigating materials on the success revascularization of necrotic mature teeth associated with PRF.

Nano-propolis and Propolis will be used as final endodontic irrigants and will be compared to saline in Revascularization of necrotic mature teeth.
